Liver shear wave elastography: the problem of accuracy and reproducibility
... stiffness measurements using shear wave elastography (SWE), as well as on the reliability of judgments about the norm and pathology. The tasks included analyzing the factors affecting the accuracy of measurements of liver stiffness depending on the equipment; testing various SWE techniques for their advantages and disadvantages; identifying the factors depending on the patient (body mass index, gender, respiration, etc.); finding out the reproducibility of liver stiffness measurements in SWE, ...
Normal range of liver stiffness measurement in healthy people
... normal values. Consensus is needed on the subject of normal values of the liver stiffness measurements and shear wave velocity in the liver tissue. Considering the discrepancy between the results of normal liver stiffness values in the sonographic equipment of various manufacturers dynamic observation upon liver stiffness values should be performed using the same machine in the same individual on the depth of 2—5 cm from liver capsule, preferably by the same operator. Caution should be given ...
The impact of lighting modes in urban environment on adaptation capabilities of young people: an ecological aspect
... study focuses on changes in adaptive processes in the bodies of young people exposed to different lighting conditions—natural illumination and complete absence of light. The research employed heart rate variability (HRV) analysis using specialized equipment (Omega-M). The obtained data indicate significant differences in the functioning of the main regulatory systems of the body under changing lighting conditions. The study reveals that artificial light exposure disrupts normal biorhythmological ...
Russian military engineers in the Prussian campaign of 1757— 1762
... under the command of D. I. Debosket in the army of S. F. Apraksin on the territory of Prussia during the Seven Years' War. It is shown that as the province was occupied by Russian troops, the engineering tasks were changing: there was a transition from equipping the track infrastructure to restoring defensive facilities. Restoration work was complicated by a variety of circumstances, including the lack of military engineers in the field due to their presence at the front line, the limited possibility ...
